Chapter 23 Advanced Fire Suppression Flashcards
(28 cards)
An offensive fire attack initiated by an exterior, indirect handline operation into the fire compartment to initiate cooling while transitioning into interior direct fire attack in coordination with ventilation operations
Transitional attack
A general descriptor for hazardous fire conditions, including flashover, backdraft, smoke explosion, flameover, and rapid fire spread
Hostile fire event
A solution based on fluorinated surfactants plus foam stabilizers to produce a fluid aqueous film for suppressing liquid fuel vapors
Aqueous film-forming foam
Foam for use on fires in Class A fuels
Class A foams
Actions that are intended to control a fire by limiting its spread to a defined area, avoiding the commitment of personnel and equipment to dangerous areas
Defensive operation
A concentrate used for fighting fires on water-soluble materials and other fuels destructive to regular, AFFF, or FFFP foams, as well as for fires involving hydrocarbons
Alcohol resistant foam concentrate
A foam application method that directs the stream into the air above the fire and allows it to gently fall on the surface
Rain-down method
A protein-foam solution that uses fluorinated surfactants to produce a fluid aqueous film for suppressing liquid fuel vapors.
Film forming fluoroprotein foam
A protein-based foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket
Protein foam
The foaming agent as received from the supplier that, when mixed with water, becomes foam solution.
Foam concentrate
A foam application method that applies the stream onto a nearby object, such as a wall, instead of directly onto the surface of the fire. Also referred to as the bank-shot or bank-down method
Bounce off method
A type of attack employing both direct attack and indirect attack methods.
Combination attack
A covering of foam over a surface to insulate, prevent ignition, or extinguish the fire
Foam blanket
An acronym intended to be used by the first-arriving company officer to accomplish important strategic goals on the fire ground
SLICE-RS
(Size-up, Locate the fire, Isolate the flow path, Cool from a safe distance, Extinguish, Rescue and Salvage at any time in the process)
The manual addition of foam concentrate to a water storage container or tank to make foam solution
Batch mix
Foam intended for use on Class B fires
Class B foams
A device installed on a fire pump that meters out foam by pumping or injecting it into the fire stream
Foam injector
Actions generally performed in the interior of involved structures that involve a direct attack on a fire to directly control and extinguish the fire
Offensive operation
Firefighting operations involving the application of extinguishing agents to reduce the build-up of heat released from a fire without applying the agent directly onto the burning fuel
Indirect attack
Solution produced by introducing a measured amount of foam concentrate into a given amount of water in a storage tank
Premixed foam solution
A protein-based foam concentrate to which fluorochemical surfactants have been added
Fluoroprotein foam
A device that uses the Venturi principle to siphon a liquid into a water stream. The pressure at the throat is below atmospheric pressure, allowing liquid at atmospheric pressure to flow into the water stream
Eductor
A foam application method that involves sweeping the stream just in front of the target. Also referred to as the sweep or roll-on method.
Roll-in method
A homogenous foam produced by the combination of water, foam concentrate, and air or nitrogen under pressure
Compressed air foam
